The journey from the first generation of cameras to the present day has seen remarkable advancements in camera technology. Progressing from black and white to color, from conventional bullet cameras to all-in-one units, from analog to digital, and from standard definition to high definition, cameras have undergone a significant transformation, especially in the realm of security and surveillance.   A camera primarily consists of a lens, an image sensor, and a digital signal processor (DSP). The lens focuses the captured image onto the sensor, which is composed of an array of X-Y arranged pixels. Each pixel...

Blacklight cameras utilize a unique technology that distinguishes them from thermal infrared imaging and low-light night vision. While thermal infrared imaging can only display the thermal silhouette of people and objects without revealing their true appearance, low-light night vision requires some moonlight or starlight to capture images, making it ineffective in complete darkness. Additionally, using infrared light for illumination may lead to exposure and potential risks of detection, as the images can be distorted due to interference from other light waves. Blacklight cameras, however, stand out as the only night vision cameras that can operate without...

The fundamental principle of cameras is to convert optical image signals into electrical signals for storage or transmission. Cameras come in various types, including surveillance cameras and ordinary cameras. But what sets surveillance cameras apart from their regular counterparts? Let's explore the differences and similarities between these two categories.   **Similarities:**   Both surveillance cameras and ordinary cameras are capable of real-time monitoring and capturing images for specific scenes, possessing some level of surveillance capability. They share a common imaging principle, differing mainly in the type of sensor used. Both employ auxiliary light sources, with ordinary...
